Cleaning the drain pump and
non-return valve
If the water has not been pumped away
at the end of a programme the drain
pump or the non-return valve might be
blocked. They are, however, easy to
clean.
Disconnect the dishwasher from the
mains supply. Switch off at the mains
socket and withdraw the plug.
Take the filter combination out of the
wash cabinet (see "Cleaning and
care", "Cleaning the filters").
Scoop the water out of the cabinet
using a suitable container or utensil.
Press the catch for the non-return
valve inwards
.
Lift out the non-return valve
and
rinse well under running water.
Remove all foreign objects from the
non-return valve.
The drain pump is situated under the
non-return valve (see arrow).
Remove all foreign objects from the
drain pump carefully (watch out for
glass splinters which are particularly
difficult to detect). Turn the drain
pump impeller by hand to check that
there are no more obstructions. You
will feel a little resistance when you
turn the impeller.
Carefully replace the non-return
valve.
Ensure that the catch engages
correctly.
Be very careful not to damage
sensitive components when cleaning
the drain pump and the non-return
valve.
